So for those of you who have been having issues getting two-factor to work, uh, (blushing) you should try that again. I forgot to configure time syncing on the server, and it had gradually drifted about 90 seconds out of sync with the actual time. Thanks to fellow server admin and mod MostlyBlindGamer for performing the incantations required to tell the server that we do, in fact, need it to keep the correct time. As each two factor code is only valid for 30 seconds, this could have been an issue for you if your computer’s clock wasn’t off by a similar amount as our server’s clock. Turns out the clock on my laptop is also off by 50 seconds or so, so it wasn’t causing any problems for me, meaning I couldn’t reproduce the bug whenever I got complaints. Anyway, it’s fixed now, and it will stay fixed in future! These are the adventures you have when you run servers for other people, but only do it as a part-time hobbyist rather than a professional system administrator. I’m really glad I didn’t file a bug on the Lemmy github complaining about how two factor still doesn’t work. Yikes.
